FIRE PLACE-GRATE Specification of Letters Patent.

Application filed May 14, 1908.

Patented July 20, 1909.

Serial No. 432,886.

grates and refers to an improved structure thereon and a damper and regulating means in connection therewith.

An object of the invention is to provide a device of this character that can be readily set up in position and that will be very simple in construction and in the assembling of its iparts.

further object is the construction an operation of a damper which is attached to the grate structure for the purpose of shutting off the draft if required.

The invention has'also the object of producing a knock down fireplace that can be removed from or installed in any ordinary chimney with comparative ease and accu- Other objects and advantages will be apparent from the following description, and it will be understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a front elevation of the device, Fig. 2 is a vertical section of the same, Fig. 3 is an elevation of the fire back, Fig. 4 is a rear elevation of the grate, Fig. 5 is an end elevation showing the manner in which the end plate interlocks with the front plate, Fig. 6 is a side elevation of one of the end plates detached, Fig. 7 is an edge view of one of the plates.

Referring now to the drawings, 10 designates a fire back which is made from sheet metal and which is longitudinally corrugated to within a short distance of the bottom where a plane surface 11 is formed. Across the line of the joining of the corrugated surface and the plane surface 11 is positioned a rib 12 which sup orts the back end of a grate 13. The fire bac r 10 has a slight longitudinal curvature, in the form of an ogee, as shown in Fig. 2, directed toward the upper end of the frame plate. The frame plate 14 is three sided and extends over and around the fireplace, and has a plurality of upwardly projecting hook ears 15, disposed in pairs on opposite sides near the inner edge of the frame. The ends comprise the metallic lates 17 and 18 which below, end in the ranges 19, as shown in Fig. 7., these flanges being inwardly directed. These end plates are also provided with a plurality of hook cars 20, which are disposed on the inner face of said end plates, and along the front edges, and are adapted to engage in the hook cars 15, formed on the rear face of the frame plate 14.

In Fig. 6 I show an end plate disclosing the hook ears 20 arranged along the front vertical edge, and the hook ears 21 disposed along the rear vertical edge.

The fire back 10 is provided with the hook ears 22 projecting laterally therefrom, which engage the cars 21 carried by said end plates 17 and 18 for the purpose of holding said back 10 in position. Slidably disposed upon the flanges 19 is an ash pan 23 which is adapted to be drawn forward through'the bottom of the cutaway portion 16 when the accumulated ashes are to be removed. The grate section 13 is sup orted upon the rib 12 at the back end and is ield at the front end against the inner face of the frame late 14. The upper portion of the grate, w ich comprises the horizontally disposed bars 24 is carried by the vertically disposed supporting bars 26 which are located at the ends of said bars 24 and adjacent to the end plates 17 and 18 respectively. The studs 25, whichare formed upon the inner side of said end plates 17 and 18 engage in the undercut lugs 40 which are carried upon the rear faces of said vertical sup orting bars 26.

T 1e damper used in connection with this grate comprises a plate 27 which is hinged to a flange 28 formed upon the inner side of said frame plate 14 at the upper end. Secured to this damper late 27, is a lug 30, from which extends a 111k 29, secured at its forward'end to the operating lever 33. This lever 33 extends through a slot formed in the frame plate 14, the rack of said lever engaging the frame plate. The frame 14 carries a rearwardly extending horizontally disosed flange 35 which serves to sup ort said 'rame plate 14 in position against tl e breast 36 of the chimney. The ash pan 23 is of such dimensions that it completely fills the space beneath the grate 13 and to allow for the proper draft to maintain a fire on said grate 13 an outwardly extending li 37 is formed upon the upper front end of t e ash pan 23, for admitting the passage of air to the under side of said grate. The ordinary hood 38 is secured to the outer face near the top of the frame plate 14 to assist in the guidance of the smoke and flames from the fire on said grate up the chimney.

It can readily be seen that when the grate which comprises the usual front and bottom sections is to be set up in position the frame late 14 is first secured in position to the hreast 36 of the chimney by means of the flange 35. The end plates 17 and 18 are then secured to said plate by the interlocking hook ears 15 and 20. The fire back 10 is then positioned and held in such position by the aterally extending hook ears 22 in engagement with the ears 21 which are carried on the rear edges of the end plates 17 and 18. The lower grate section 13 is then placed upon the horizontally disposed rib 12 at the back end and is sup orted at the front as has been described e remaining grate section, comprises the bars 24 and side members 26 and this grate section is held to the studs 25 which are disposed on the inner surfaces of the end plates 17 and 18. The ash pan 23 is placed under the grate 13 upon the flanges 19 and can be withdrawn readily from such position beneath the grate 13 by virtue of the sliding engagement of said ash pan 23 upon saidflanges 19. The upper flange 28,

it will be noted, extends at right angles from the face plate 14.

What is claimed is:

'A fire lace grate having in combination, 'a three sidbd frame plate having an inwardly directed horizontally disposed flange near its upper edge, and hook ears near its inner verti cal edges, two end plates provided with hook ears along both vertical edges, the hook ears along the front vertical edge of each end plate interlocking with the corresponding hook ears of said frame plate, a fire back made of sheet metal the major portion being longitudinally corrugated, said fireback having a slight longitudinal curvature in the form of an ogee, said fire-back being of a length less than said end plates and having hook ears interlocking with the hook ears of said end plates upon the rear vertical edges, said end plates being shaped to conform to the longitudinal curvature of said fire-back, f

a damper secured to said horizontal frame flange between said end plates and resting upon the upper edge of said fire-back, and an operating lever extending from said damper and through said frame plate, as and for the purpose set forth.

In testimony whereof I afiix my signature, in presence of two witnesses.

JAMES H. DWIGHT.
